Adafruit I2C to 8 Channel Solenoid Driver - STEMMA QT / Qwiic
Adafruit Industries, LLC mail
We designed the Adafruit I2C to 8 Channel Solenoid Driver featuring an MCP23017 GPIO expander to make eight solenoids at a time easy and solder-free. This board has an I2C to GPIO expander - so you can use it even if you don't have a lot of pins on your microcontroller. Power the solenoids with a DC power supply in the center terminal blocks, you can use 3V to 24V DC maximum. Then wire up each solenoid to the remaining terminal blocks. The positive side will tie to the power supply you provided, and then the negative side will connect to ground when activated. Each solenoid has its own pass transistor AO3406 N-Channel MOSFET rated for 30Vds, 3.6A peak, and 70m ohm RdsOn. A flyback diode protects your circuit from the inductive kick-back, and a red LED will light up to let you know that the transistor is on.
